Wicked_Lex Posted September 10, 2005 Posted September 10, 2005 I have a GS400 and I would like to improve 0-60 and 1/4 mile times. I have heard a lot about Swift's intake/ECU piggy back system. Their wesite boasts of 30 HP and torque gains. Is that realistic? :) Does anyone have any before/after dyno charts that they could share? I am also interested in what negative effects, if any, this system would have on fuel econony since premium unleaded is selling for over $3/gallon in Cailfornia. :cries:
